Ingredients
  

Ingredients
  • 2 large White Onions Sliced into 3/4-inch rings
  • 1.5 cups All-Purpose Flour 180g
  • 0.5 cup Cornstarch 64g
  • 1 tsp Baking Powder 5g
  • 1 tsp Smoked Paprika 2g
  • 1 tsp Cracked Black Pepper 2g
  • 1.25 cups Club Soda 300ml, Ice Cold
  • 1 quart Vegetable Oil 950ml, for frying
  • 1 tbsp Fresh Parsley Finely chopped for garnish
  • 1 tsp Flaky Sea Salt To taste

Equipment

  • 1 Dutch Oven or Deep Skillet For deep frying
  • 1 Digital Thermometer To monitor oil temperature
  • 1 Spider Strainer For safe removal

Method
 

Prep and Dredge
  1. Soak the sliced onion rings in ice water for 10 minutes, then pat dry thoroughly.
  2. Whisk dry ingredients and toss the dry onion rings in the mixture to create a primer coat.
Fry to Perfection
  1. Add ice-cold club soda to the remaining flour mix and whisk until just combined.
  2. Heat oil to 375°F (190°C). Dip rings in batter and fry for 2-3 minutes per side until bubbly and golden-brown.
  3. Drain on a wire rack and immediately sprinkle with flaky sea salt and chopped parsley.

Notes

Ensure the club soda is truly ice-cold for the best bubbles.
Always use a thermometer to maintain 375°F to prevent greasiness.
